This is really cool as well, I was sent this in exchange for an honest review. Steam cam out easy and FAST after plugging in. Instructions state works 6-9 min, then you need to wait 10 min before refilling and using again. You can adjust the steam particles to be smaller for inhaling through nose or larger for mouth breathing. If using your nose to breath in the large amount it was a little warm on my nose. Worked well and in the couple minutes I tried this (yes… in the TRUCK) my nose was already letting down mucous and clearing!!!!
